A giant exoplanet is surprisingly chill given how close it is to its red dwarf star — perhaps because the star is so little.

Astronomers want direct images of exoplanets. They may need 'quantum-level' tech to get them
By Victoria Corless published
A new device uses quantum optics to filter out starlight in real time — bringing scientists closer to directly observing Earth-like worlds.

Lightning on alien worlds may fail to spark life, simulations suggest
By Paul Sutter published
New research has found that lightning, while not very common, can occur on tidally locked exoplanets like our nearest neighbor, Proxima b.
